Wood stoves are simple, convenient, economical and environment- friendly appliances used to heat your home. In the recent decades much research and development has been dedicated to wood stoves to make them more efficient and less harmful for the environment. More specifically, wood stoves nowadays are state-of-the-art appliances which have the capacity to heat an entire house; of course they can also be used as secondary zone heaters. Wood stoves are designed to produce almost no smoke and to burn the wood entirely. In addition they produce minimal quantities of ash and usually require relatively little amounts of firewood. What is more, wood stove’s construction is extremely air tight and durable, with clearances to walls that can in some instances be as little as six inches.
